Deformed Battery housing

Has anyone else had this problem, I woke up this morning to find my battery housing has deformed and I am wondering if this will be a warranty thing as my computer is only two years old.

I haven't had it happen to me, but I know of others who have. That is a defect in the battery. Certain MacBook and MacBook Pro models are subject to a warranty extension due to manufacturers defects. Contact Apple for a replacement.

There's an Apple page on this but it won't load so look at
